Air Conditioner Definite Purpose Contactors Two Poles

The contactor is the part of the air conditioner that controls the flow of electricity into the unit. When you turn off your AC, the contactor goes up, blocking power. By the same token, every time you turn on the air conditioner, the contactor is lowered, allowing electricity to power the system.

Air Conditioner Contactor, 2 Pole Replacement
This contactor is a replacement for many brands of outdoor air conditioning condenser units. The universal mounting base allows replacement of most contactor brands.
Operation of 2 pole contactor
The contactor connects the outdoor unit to 110/220 volt power causing both the compressor and the outdoor fan motor to run.  The 2 pole contactor disconnects both legs of the 110/220 volts (cuts all power).  A 1 pole contactor in contrast leaves one leg of the 110/220 volts connected even when the outdoor unit is not running. The contactor is controlled by the indoor thermostat which uses 24 volt power to energize the contactor and connect 220 volts to run the compressor and fan motor.
